Re: Converting a 110v watermaker to 12v DC?

Water in equals supply and the demand for the pump. Not enough water = low pressure. All other concerns (amp draw and hp ) don't matter if you cant feed the pump. If you put a smaller pump you still have the problem of water in and water out. It takes about 8 gals of salt water to make one gal of fresh water, the membranes are sized to fit the output of the hi pressure pump so you could get smaller membranes or take one out ,if it has more that one.All of this being said keep what you got and use as is or get a 12 lt system. Hope this helped some.GARY
Well, not really... it just has to reach adequate speed. He could put it on the main diesel engine and just run at a convenient speed. (which I have done)
